Term Description

The IEEE 11073 Standards Committee does not distinguish between measures of gas concentration reported as partial pressure and volume percent because they can be converted from one to the other under the law of gases. To make it clear that these could be reported either way, LOINC presents the property for these terms as both a volume fraction and a partial pressure (VFr/PPres), with corresponding units of %{vol} and mm[Hg], respectively.

Part Description

LP15150-3   Carbon dioxide
CO2 content is a measurement of total CO2 in the blood. Most of it is in the form of bicarbonate (HCO3) controlled by the kidney. A small amount (5%) of CO2 is dissolved in the blood as insoluble carbonic acid (H2CO3). Changes in CO2 content generally relate to metabolic issues, renal function and unusual losses (diarrhea). Respiratory disease can ultimately effect CO2 content, but only slightly and only if prolonged.

Change Reason
Changed System from "Airway" to "Airway adaptor" to clarify meaning per IEEE 11073:10101a standard and to distinguish the "Airway adaptor" device from "Respiratory system.airway", which is the airway portion of the patient respiratory system.
